H, Li, Na, K = 1valence electrons
Be, Mg, Ca = 2 valence electrons
B, Al = 3 valence electrons
C, Si = 4 valence electrons
N, P = 5 valence electrons
O, S = 6 valence electrons
F, Cl = 7 valence electrons
He, Ne. Ar = 0 because they are noble gases and all their electron shells are full

What is the maximum number of covalent bonds an element with atomic number 7 can make with an element with atomic number of 16?
It can make maximum 2 covalent bonds as element of atomic number 7 has 5 valence electrons while element having 16 atomic number have 6 valence electrons.
What element has an atomic number of 94?
Actinium is a meta element. Atomic number of it is 89.
What is the valency of elements?
The valency of an element is the number of electrons an atom of that element wants to gain, lose or share in order to be chemically stable.
Does each element have a unique atomic number?
Yes. The atomic number is the number of protons in the nuclei of an element's atoms, which is unique to each element and determines the element's identity.
The atomic number determines the what?
The number of protons.
An element having atomic number 14 its valency will be?
Its valency could be 4 because it has 4 electrons in its valence shell.
Atomic number of an element is16 what is its velency?
The element with an atomic number of 16 is sulfur. Sulfur has a valency of -2 as it is in group VI.
What is the valency of an element with atomic number 8?
Carbon has a valency of 2, 4. Which might be useful information if it were either a) correct or b) relevant (the atomic number of carbon is 6). The element with an atomic number of 8 is oxygen, which has a valence of 2 (and a most common oxidation number of -2).
What is ceric mean?
Ceric is an adjective that describes the element cerium in its higher valency. Cerium is a silvery white metal element with an atomic number of 58.
What is the periodic table is organized according to?
Atomic number, the number of protons, and the similarity of chemical properties
Which element has an atomic number of 6?
Carbon is a none metal element. atomic number of it is 6.
Which element having atomic number 13?
The element with the atomic number 13 is aluminum.
Which element has the lowest atomic number of group 16 elements?
Oxygen is the element having atomic number 8. It is present in group-16.
What is the meaning of valency?
Valency (in chemistry) is the number of the valence bonds of a chemical element.
What is the maximum number of covalent bonds an element with atomic number 7 can make with an element with atomic number of 16?
It can make maximum 2 covalent bonds as element of atomic number 7 has 5 valence electrons while element having 16 atomic number have 6 valence electrons.
How do you find valency?
The valency of an element measures its ability to combine with other elements. This valency is determined by the number of electrons in the outer shell of each atom of an element.
How do you take out valency an element?
Group number 1 = Valency 1+group number 2 = valency 2+group number 3 = valency 3+group number 4 = valency 4+ and 4- (some cases) group number 5 = valency 3-group number 6 = valency 2-group number 7 = valency 1-group number 8 = valency 0For the transition elements they will either state Copper (III) Sulphate or it will be like Cu2(SO4)3You can find the valency by the base of sulphate and you know its positive because metals are always positive and are written in the left.Source: I am a GCE O Level Sciences Student (O2)
